Trying to add to a User-to-User header in INVITE
Need to add a descriminator code to data because of difference in sender and receiver use of UUI data.
Need to add to : User-to-User: 30313130303031323633383135303739;encoding=hex
So it looks like :User-to-User: 0430313130303031323633383135303739;encoding=hex
The INVITE looks like:
